Evaluating efficacy of selected alternatives for dissolving Flexcon's 1304, 7777, 1565, and 7244 proprietary coatings and adhesives.
Date Run:
01/12/2026
Experiment Procedure:
Fifteen 25 mL scintillation vials were filled with Benzaldehyde, Benzyl benzoate, 2-Pentanone, and D-limonene (3 vials of each). The four soils were then prepared by spreading them on wax paper and allowing them to air dry to a consistency that could be balled up with a pair of tweezers. Each of the four soils were prepared this way and then a single ball of similar size was placed in each scintillation vial and placed on the experimental roller. Observations were recorded every 10 minutes for the first hour and then every half hour until the three hour mark. Observations included whether or not the solvent had dissolved the soil above or below 80% and other visual criteria, such as whether the solvent changed color or became cloudy.

Success Rating:
Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.
Conclusion:
Based on the results of this test, Benzaldehyde was the most successful solvent and was able to dissolve 3 of the 4 soils. None of the four solvents were capable of successfully dissolving the 1304 Acrylic topcoat. 2-Pentanone was second behind Benzaldehyde, able to dissolve 2 of the 4 soils. Neither d-limonene nor benzyl benzoate were successful in dissolving any of the soils.
